Testing of Laptop Adapter
We have taken a laptop adapter for testing using DTM-1.
Specifications are as below:
- Input: 100-240 Volts 1.5A
- Output: 19Volts 3.42A
We have made the testing specifications as below:
In the software we have set the limits according to the requirements as below:
Setup
We have connected a laptop as load.
Main Page (AC+DC+THD)
This page shows AC- Voltage, Current, Watt and current THD % in first column. Second column shows DC Voltage, Current, Watt and Efficiency.
We have see here that efficiency of this laptop adapter is 90.77% whereas Current THD is 35.27%.
AC Parameters
This page shows AC parameters. On first column it shows voltage, current, watt and frequency.
Second column shows Vthd%, Athd% and NET THD.
DC Parameters
This page shows DC Voltage, Current, Watt and Efficiency.
